ADDERLink XD612
models use a single DisplayPort link to accept up to two
video feeds from the host computer. This combined MST stream is then transferred
to the receiver where an internal MST hub separates the two streams and presents
them individually at the two video output ports.
All but the final video display in the chain on the XD614 receiver must specifically
support MST on DisplayPort 1.2 or later. These displays will each have a DP output port
to allow the daisy-chain link to continue to the next. The last video display in the chain
does not need to support
MST as it is the final destination for the video signals.
Note: Check that the video card and display specifications support the required number of daisy-
chained displays.
Support for multiple non-MST video displays on XD614
If you are using multiple video displays with the XD614 receiver that do not support
MST, there are a couple of options:
• You can optionally enable an internal hub within the XD614 receiver which will allow
non-MST video displays to be connected to the two output ports so that they can use
the first and second video streams respectively. See
•
You can optionally use an external MST hub, which will receive the combined
DisplayPort signal from the first video port on the receiver and split out separate links
to the standard video displays (see next page).
Notes:
When using more than one video
display, the host’s video adapter,
operating system and applications
must support MST.
Windows™ and Linux fully
support MST, however, no devices
manufactured by Apple
®
currently
support it.

models use a single DisplayPort link to accept up to
four video streams from the host computer. This combined MST stream is then
transferred to the receiver, where you can connect multiple video displays in a
daisy-chain (or via a third-party MST hub) from the primary video output port:
Notes:

display, the host’s video adapter,
operating system and applications
must all support MST.

MULTI-DISPLAY SUPPORT USING MST
The ADDERLink XD612 and 614 models support the MST (Multi-Stream Transport) protocol, which was introduced in the DisplayPort 1.2 standard. MST allows feeds
for multiple video displays to be fed along a single cable. The XD612 and XD614 models use this feature in different ways.
The video displays do not need to be
MST-compliant and no hub is required.
